| This is an unusual mode of feeding for echiurans, and most use their proboscises to move sedimentary detritus to their mouths. |
|
| When the hawk moth proboscises were long compared to the length of the flower tube, the hawk moths did not efficiently pick up pollen, and the flowers did not reproduce well. |
|
| Eventually, bees extended their tonguelike proboscises when exposed to the scent alone. |
|
| Thousands of trials were performed over 18 months at the installation's nuclear weapons laboratory during which bees stuck out their proboscises when they smelled explosives. |
